RFX MIDI PHANTOM POWER Inspired by an article in the December 1989 issue of Electronic Musician (by Craig Anderton), we decided to emulate their MIDI phantom power model for RFX equipment. MIDI receivers supply 12 VDC on pins 1 and 3, and transmitters receive power on those same pins. Many MIDI devices can be modified to supply power down the cable, but of course RFX makes no warranty to anyone as to the applicability of this modification or any dam age that might be done as a result thereof. We supply this note for those adventurous people who may want to give it a try. Connect pin 1 to circuit ground, and pin 3 to +9 - +15 VDC of the receiving unit.

OWNERS MANUAL

INTRODUCTION Thank you for purchasing the RFX MP128 MIDIBUDDY. The MP128 sends standard MIDI program changes to select patches on a MIDI keyboard, digital signal processor, or other MIDI controllable device. DESCRIPTION

through banks 0 through 120. The ones digit is selected by switches 0 - 9. MIDI data is sent only when a 1 - 9 button is selected except as described below. The display will show a "-" in the right hand digit when no MIDI information is sent,or when a 10's UP or DOWN button is pressed. For example; to send program 47, press the 10s UP or 10s DOWN until the display reads "4-" then press the 7 button. When the 7 button is pressed, program 47 is sent out and the number is displayed by the LED readout. MIDI Start and Stop Commands When program "00" is selected, the MP128 display shows an "ST" (which looks more like an Sr), and sends a MIDI start command. This may be used to start a MIDI sequencer. When program "129" is selected, an "SP" is displayed and a MIDI Stop command is sent.
A. Program Select, Function buttons B. Program/Function Display Window C: 127/128 (Dip switch #6) Switch D: PROGRAM CHANGE/SONG SELECT (DIP switch # 5) Switch E: MIDI CHANNEL SELECT Switches (DIP switches 4,3,2, and 1) F: SHARE output G: MIDI output jack H: POWER jack INSTALLATION Apply power (Rolls Model PS27, 12VDC, 150mA) to the Power jack on the rear of the MP128. The MP128 may also be "phantom-powered" which means powering the unit via unused pins of the MIDI cable. See the back page of this manual for more on MIDI phantom power. Connect the MIDI OUT of the MP128 using a standard MIDI cable, to the MIDI IN on the device to be controlled. The MIDIBUDDY may be used on the floor and foot switched or placed on top of a keyboard for easy hand access. The unit, with slight modification, will fit in a standard 19 inch audio rack if necessary. The "SHARE" jack is in parallel with the OUT jack and operates as a MIDI "Thru" for connecting several devices together. For example, two MP128s operating on different MIDI channels could use the same MIDI path. OPERATION The MP128 follows MIDI standard protocol, and will change programs on any MIDI controllable device. The controlled device and the MP128 must be on the same MIDI channel (see chart - next page), or the device should be on an "omni" channel. The unit sends up to ten different program changes, in twelves different banks. Bank 0 sends program changes 1 - 9 (there is no program change 0), bank 1 sends program changes 10 - 19, bank 2 sends program changes 20 - 29, etc. The LED display on the MIDIBUDDY shows the MIDI program number (0 - 127, or 1 - 128 depending on the setting of DIP switch # 6). As the 10s Up or Down are scrolled through, the unit increments or decrements

Setting the DIP Switches NOTE: DISCONNECT THE POWER CABLE TO MAKE DIP SWITCH CHANGES. SETTINGS TAKE EFFECT UPON POWER-UP. The MIDI Channel is set with DIP switches 1 - 4 on the rear of the MP128. If all switches are in the off position, MIDI channel 1 is selected, if all are on, MIDI channel 16 is selected. Use the following chart to select the MIDI Channel. CH# ON OFF CH# ON OFF 1 1,2,3,4 1,2,1 2,3,1,4 2,2 1,3,2,4 1,1,2 3,1,2,1,2,3,4 1,1,3 2,1,3,7 2,3 1,2,3,8 1,2,16 1,2,3,4 Switch #5 selects whether the MP128 transmits Program Change information only, or transmits Program Change and Song Pointer. Since some MIDI devices display their programs as 0 - 127, and others display 1 - 128, the MIDIBUDDY's DIP switch #6 will select either of these two. If switch #6 is in the off (up) position, the MP128 will display program numbers 0 - 127. If switch #6 is on (down), the MP128 will display program numbers 1 - 128 (which is the way the MP128 comes from the factory).

JANUARY 2010

A preview of new products
New products and updates to existing products we are working on: We are now working on a product that is so new we do not even have a part number for it yet. It is a powered monitor speaker in a single rack space chassis. We are in the concept stage of design and have not finalized if it should be mono or stereo. It will have a headphone monitor output on the front and a selector switch to monitor inputs. Yes it will have actual speakers built in to the front panel of the unit. We would like some input if you are familiar with rack space speaker monitoring.

WHATS NEW?

New color for the VP530!

NOW SHIPPING!!

AS OF JANUARY 13 WE ARE SHIPPING THE NEW MX410!!!
We are now shipping the VP530 in black. All orders will now be shipped with the new color. Please let everyone know of this change.
**************************
New chassis design for the MP128
Yes, they are finally shipping!!! We have the first production completed and have shipped almost half of the run already. We started the second production run last week. They are in stock and shipping now!!!
The MP128 has a redesigned chassis. We made the bottom row a little larger to accommodate actual silk screened numbers rather than the old version that had a sticker for the bottom row. All other stats for the MP128 remained unchanged it functions exactly like the old version. The price is unchanged.
In 2009 we shipped a total of 6442 orders and sold 60727 pieces of Rolls equipment.
